Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of machine-building. And more particularly to a chuck for use in clamping a workpiece on a lathe.
[ background of the invention ]
At present, a chuck is one of indispensable important parts arranged on a lathe for clamping a workpiece. The chuck is divided into three claws and four claws. When the rotation center line of the four-jaw chuck used for the processed surface is inconsistent with the actual center line of the processed workpiece, the center offset position of the processed workpiece needs to be determined, a special wrench is used, the positions of the four jaws are respectively and independently adjusted, and the four-jaw chuck can be clamped in time and is firm. The three-jaw chuck has an automatic centering function, and is used for clamping a machined workpiece when the rotation center line of the machined surface is consistent with the actual center line of the machined workpiece, the three-jaw chuck can automatically center, and a special wrench is used for clamping and fixing the machined workpiece in one operation. The chuck has multiple model, has the restriction to the tight size of work piece clamp to realize through the three-jaw that sets up on the chuck. The three claws are divided into an inner three claws and an outer three claws. In the production practice, when the three-jaw adjustment can not meet the requirement, the chuck is frequently replaced to meet the requirement of machining and clamping when the shape and the size of a workpiece to be machined are larger. The disadvantages are as follows: the chuck is frequently replaced, a standby chuck needs to be configured, the labor intensity of workers is increased due to replacement of the chuck, the auxiliary working hours are increased, the production efficiency is reduced, and the production cost is also increased.
[ summary of the invention ]
The utility model aims to provide an outer three-jaw and be provided with chuck of outer three-jaw. The clamping device does not need to be provided with a spare chuck, meets the requirement of machining and clamping when the shape and the size of a machined workpiece are larger, reduces the labor intensity of workers, reduces the auxiliary working time, improves the production efficiency and reduces the production cost.
The technical scheme of the utility model is that:
1. an outer three-jaw, comprising: the automatic centering claw system is composed of an outer three-claw a101, an outer three-claw b102 and an outer three-claw c103 which are equally distributed according to the circumference and correspondingly assembled according to the sequence number, and is characterized in that:
the outer end part of the outer three-jaw a101 is provided with a tooth jaw d1011 which is convex outwards and convex forwards along the direction of the centering axis thereof,
the outer end part of the outer three-jaw b102 is provided with a tooth claw e1021 which protrudes outwards and protrudes forwards along the direction of the centering axis thereof,
the outer end portion of the outer three-jaw c103 is provided with a tooth claw f1031 which protrudes outward and protrudes forward in the direction of the centering axis thereof.
Meanwhile, a clamping step g1012 in a rectangular notch shape is arranged at the inner side of the front end of the tooth claw d1011,
meanwhile, a clamping step m1022 in the shape of a rectangular notch is arranged at the inner side of the front end of the tooth claw e1021,
meanwhile, a clamping step n1032 in a rectangular notch shape is provided at the front end inner side of the tooth claw f 1031.
2. The utility model provides a be provided with above-mentioned chuck of outer three-jaw which characterized in that: the chuck 1 is a round cake-shaped self-centering chuck with a transverse axis, and concave trapezoidal slots which are correspondingly assembled with the outer three-jaw a101, the outer three-jaw b102 and the outer three-jaw c103 in sequence are uniformly distributed on the end face of the right side of the chuck 1.
The assembly and disassembly can be adjusted by using a chuck wrench.
An outer three-jaw and be provided with chuck of outer three-jaw, only changed the structure of outer three-jaw. No spare cartridge is required. The requirement of processing and clamping when the shape and the size of the processed workpiece are larger can be met.
The utility model has the advantages as follows: by adopting the technical scheme, the technical effects of reducing the labor intensity of workers, reducing the auxiliary working time, improving the production efficiency and reducing the production cost are achieved. The utility model has simple structure.
